Shohei Ohtani is excited about the Angels’ aggressive approach in a push to end a lengthy postseason drought.

And he took his game to another level on the field to prove it.

A day after the Angels confirmed they would be buyers, Ohtani did it all on both sides of the ball during a doubleheader against the Tigers.

In Game 1, he threw his first-ever shutout in the Angels’ 6-0 win.

He followed it up with two homers in the second contest, before being removed from the 11-4 win in the seventh inning because of cramping.

The Post’s Jon Heyman confirmed Wednesday night that the Angels were taking the two-way superstar off the market ahead of the Aug. 1 trade deadline in an effort to be buyers for a playoff push.

And sticking to that plan, the Angels acquired starter Lucas Giolito and reliever Reynaldo Lopez for two prospects in a trade with the White Sox right before midnight on Wednesday.

The move gives the Angels a 2019 All-Star in Giolito, who can shore up their starting rotation while Lopez can round out the bullpen.

The 29-year-old Ohtani, who will be a free agent at the end of the season, was plenty pleased by the move as Los Angeles remains in the hunt for an American League wild-card spot.

The team has not made the playoffs since the Japanese superstar entered the league in 2018, last making the postseason in 2014 when they were swept by the Royals in the Division Series.

“I think this is the first time in my six years that we’ve been buyers,” he told reporters Thursday. “We’ve been sellers the last five years. So this is new to me. I just want to get to know the new guys and welcome them in and compete all together.”

“From the beginning, my plan was to finish the season with the Angels, he added. “Nothing is really going to change mentally, but all the people talking about the trades — that’s going to be all gone.

“I feel like I’ll just focus on taking this team to the playoffs.”

Ohtani seemed to have that focus on full display on Thursday afternoon in Detroit.

In the first game of a doubleheader, the right-hander got the start against the Tigers, going the distance in a one-hit shutout.

He struck out eight and walked three, giving up a lone single to Kerry Carpenter in the fifth inning.

Ohtani retired the final six batters he faced in his first MLB shutout — though he did go 0-for-5.

But his offensive fortunes changed in Game 2 of the twinbill.

In the second inning against Tigers starter Matt Manning, Ohtani clubbed a two-run homer to the opposite field at 107.6 mph.

Two innings later, the Angels star drilled a fastball down the middle from Manning and sent it 435 feet to right-center field for his league-leading 38th homer.

In Game 1, he finished the day allowing just one hit against and eight strikeouts in nine innings pitched for a win with two home runs and three RBI in the twin bill.

Ohtani didn’t budge on his approach to avoid talking about next year despite the recent developments.

“In season, I don’t really like to think about the long-term stuff, just focus on the season and every game that’s in front of me,” Ohtani said through a translator after the first game. “Obviously, I’ve been with the Angels my whole career here, and I love the fans. I love the team, no complaints.”

The hard-throwing righty with wicked off-speed pitches threw 111 pitches, 71 for strikes.

“I got to save the bullpen,” said Ohtani, who had previously finished eight innings five times.

Whether the Angels make the postseason or not, Ohtani is making his case for another AL MVP in another incredible season.
